Improvement in water-elevators

IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Leiters Patent No. 124,328, dated March 5,1872.

Specification describing a new and useful Improvement in Water-Elevators, invented by JOHN L. BURCH, ot' Franklin, in the county of Williamson and State of Tennessee.

Figure l is a detail vertical section of 'my iinproved elevator. Fig. 2 is a plan or top view of the same.

My invention has for its object to furnish an improved endless-chain water-elevator, which sha-ll be so constructed that it can be convenient-ly taken apart t'or increasing or decreasing the length of the chains, detaching buckets, transportation, or other purposes; and it consists in the construction and combination of parts, as hereinafter more fully described.

A represents a well-curb or house 5 and B, a discharge-trough or spout, about the construction of which parts there is nothing new. C is a hub or drinn fixed on a rotary shaft, D, that has its journals in a suitable frame located at the top of the well or cistern. E is the endless chain, composed of a series of links, each link consisting of two end bars, F, connected by a transverse bar or rib, G, and all of the links flexibly attached to each other by rods H. I are the buckets, which may be of any desired shape, but I prefer the form shown in the drawing. The buckets are detachably attached to the chain by means of plates J having hook-shaped ends, which tit over the transverse rods connecting' the chain-links. K is a loose roller or hub located at the bottom ofthe well or cistern, around which the chain passes,

. the object of the same being to balance the former and steady its movement. The roller may either be made of the desired weight or a weight, L, may be attached to it. The upper or stationary hub, G, as well as the loose one, K, are provided with grooves L on their peripheries for receiving the ribs C during the revolution ofthe chain, and th ercby preventing the saine from slipping. M is a short crankshaft, to which thel drivin g force is applied, the same being communicated to the rotary shaft carrying the hub O, by means of the small a-nd large gear-wheels N O, attached, respectively, to the crank and hub-shafts. P is a ratchetwheel on the shaft D, which, when engaging with the pawl Q, will prevent the movement of the chain in a backward direction when water is being raised. R is a pivoted arm for disengaging the pawl from the ratchet-wheel, so as to allow the chain to be. turned in a reverse direction for discharging` the water that may be in the buckets and not required for use again into the well. S a-re small-friction pressure-rollers, which are located at opposite ends of the hub C above the surface of the same,

and are intended to press the chain-links into the grooves in said hub, and thus prevent the same from being disengaged. A brake mechanism is applied to the shaft D, consisting ot` a pulley, U, a spring-band, V, and operatinglever T, attached to the lat-ter.

The inode ot' operation is as follows, viz.: The drivin g-shaft being turned will impart a rota-ry motion to the drum-shaft, which will cause the lchain to travel around the saine, and as the various buckets pass over the top ofthe drum they are inverted so as to discharge their contents into the conducting-spout leading into a suitable reservoir, &c.

From the above description it will be pereeived that a water-elevator is produced which can be applied to an ordinary well or cistern, without requiring the use of a frame extending to the bottom ot the well for the reception of the lower drum or roller; and also one in which the buckets can be easily detached from the chain, as well as the links themselves.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A water-elevator, consisting of the endless chain E, detachable buckets I, grooved stationary revolving drum C, loose grooved and weighted drum K, dri ving-shaft M, gear-wheels N O, rotary shaft D, ratchet-wheel P, pawl Q, arm R, and brake mechanism T U V, and pressure-rollers S, when all the parts are constructed and arranged as herein shown and described.
